Question

Study the following graph to answer the given questions.

Units Manufactured by two companies over the years (Number In thousands)

What is the difference in the total units manufactured by the two companies for the given years?

Options

• 20,000

• 12,000

• 7,500

• 10,000

Answer 1

10,000

Explanation:

Total units produced by Company A = (10 + 12.5 + 15 + 30 + 25) × 1000 = 92,500

Total units produced by Company B = (7.5 + 10 + 20 + 22.5 + 22.5) × 1000 = 82,500

∴ Required difference = 92,500 – 85,500 = 10,000

Calculatiom for quenlom (33 – 37) :

Number of students in course A = `1200 xx 20/100` = 240

Number of girls = `800 xx 30/100` = 240

Number of boys = 0

Number of students in course B = `1200 xx 15/100` = 180

Number of girls = `(800 xx 10)/100` = 80

Number of boys = 180 – 80 = 100

Number of students in course C = `1200 xx 5/100` = 60

Number of girls = `(800 xx 2)/100` = 16

Number of boys = 60 – 16 = 44

Number of students in course D = `1200 xx 35/100` = 420

Number of girls = `(800 xx 30)/100` = 240

Number of boys = 420 – 240 = 180

Number of students in course E = `(1200 xx 12)/100` = 144

Number of girls = `(800 xx 14)/100` = 112

Number of boys = 144 – 112 = 32

Number of students in course F = `(13 xx 1200)/100` = 156

Nuinber of girls = `(800 xx 14)/100` = 112

Number of boys = 156 – 112 = 44
